I have been doing all grain for about a year now and want to double up my batches. I am in the process of welding up a keggle. My question is when doubling a recipe do all the mash Sparge and boil times remain the same. Do I just double the recipe and follow the same process? Any info is appreciated thanks

I was just recently looking into this and what I gathered from all of the threads on here is that any batch 10 gallons or less... you can just double the recipe. When you scale recipes your main concern is hop utilization, but you won't experience enough of a difference for 5-10 gallon batches. Mash/boil time remains the same and you will have to increase your sparge volume accordingly.
